6 * runtests [-b <build-dir>] [-s <source-dir>] <test-list>
7 * runtests -o [-b <build-dir>] [-s <source-dir>] <test>
9 * In the first case, expects a list of executables located in the given file,
10 * one line per executable. For each one, runs it as part of a test suite,
11 * reporting results. Test output should start with a line containing the
12 * number of tests (numbered from 1 to this number), optionally preceded by
13 * "1..", although that line may be given anywhere in the output. Each
14 * additional line should be in the following format:
19 * not ok <number> # todo
21 * where <number> is the number of the test. An optional comment is permitted
22 * after the number if preceded by whitespace. ok indicates success, not ok
23 * indicates failure. "# skip" and "# todo" are a special cases of a comment,
24 * and must start with exactly that formatting. They indicate the test was
25 * skipped for some reason (maybe because it doesn't apply to this platform)
26 * or is testing something known to currently fail. The text following either
27 * "# skip" or "# todo" and whitespace is the reason.
29 * As a special case, the first line of the output may be in the form:
31 * 1..0 # skip some reason
33 * which indicates that this entire test case should be skipped and gives a
36 * Any other lines are ignored, although for compliance with the TAP protocol
37 * all lines other than the ones in the above format should be sent to
38 * standard error rather than standard output and start with #.
40 * This is a subset of TAP as documented in Test::Harness::TAP or
41 * TAP::Parser::Grammar, which comes with Perl.
43 * If the -o option is given, instead run a single test and display all of its
44 * output. This is intended for use with failing tests so that the person
45 * running the test suite can get more details about what failed.
47 * If built with the C preprocessor symbols SOURCE and BUILD defined, C TAP
48 * Harness will export those values in the environment so that tests can find
49 * the source and build directory and will look for tests under both
50 * directories. These paths can also be set with the -b and -s command-line
51 * options, which will override anything set at build time.
53 * Any bug reports, bug fixes, and improvements are very much welcome and
54 * should be sent to the e-mail address below. This program is part of C TAP
55 * Harness <http://www.eyrie.org/~eagle/software/c-tap-harness/>.
